Fiskars 12' Fiberglass Tree Pruner/Saw

The Fiskars 12’ Fiberglass Tree Pruner/Saw extends from 7 to 12 feet and cuts branches up to 1 inch thick with the pruner or handles thicker limbs with its 12-inch saw blade. At approximately 4.5 pounds, it’s light enough for extended overhead work — a real consideration when you’re trimming ornamental trees around Montana properties at elevation.

Skip it if you need reliable heavy-duty performance. Users report the rope can fray or snap and the plastic pulleys are prone to breaking under heavy use. The 2.3/5 rating on Fiskars’ own site tells you everything about durability concerns. This tool works for occasional homeowner use or light professional trimming. It doesn’t hold up to daily contractor abuse.

Specifications and Reach

Model numbers 393951-1005 and 393951-1007 both feature the same 7-12 foot extendable fiberglass pole. The quick-release thumb lock (or double-locking system depending on model year) secures the pole at your chosen length.

Specification	Value
Pole Length	7-12 ft (extendable)
Cutting Capacity (Pruner)	1 inch (approx. 2.5 cm)
Saw Blade Length	12 inch (double-grind)
Pole Material	Fiberglass
Blade Material	Fully hardened, precision-ground steel
Blade Coating	Low-friction, rust-resistant coating
Weight	Approx. 4.5 lbs

The bypass pruner handles thin limbs and twigs up to 1 inch diameter, while the 12-inch saw attachment tackles thicker branches. That’s adequate for most ornamental tree maintenance — crabapples, mountain ash, and the smaller maples common in Montana landscaping. Don’t expect miracles on mature cottonwood limbs.

Durability Reality Check

Users praise the lightweight design and sharp blades but consistently report issues with the rope/cable durability and plastic pulley system failing. The saw blade can wobble at full extension, and the pole may bend slightly when fully extended.

Here’s what fails first:

• Rope frays or snaps — the most common complaint
• Plastic pulleys break — especially under heavy cutting loads
• Saw blade wobbles — makes precision cuts difficult at height
• Pole bends at full extension — fiberglass flexes more than aluminum

Replacement parts are available for purchase, including replacement saw blade (Part #93356920) and replacement pruner blade (Part #399961). You’ll likely need them if you use this tool regularly.

Value Trade-offs

This is the entry-level choice in Fiskars’ lineup, valued for being lightweight but noted for having less cutting power than Power-Lever versions. The Power-Lever models (14-foot and 16-foot) offer more reach and claim 4x more cutting power.

The fiberglass construction keeps weight down compared to aluminum alternatives. That matters when you’re working overhead all day. But fiberglass flexes more than aluminum, reducing control and cutting power at full extension. Professional reviewers note the Power-Lever technology provides up to twice the cutting power — worth considering if you’re cutting anything beyond small ornamental branches.

The kit includes the 7-12 ft extendable pole, bypass pruning head, 12-inch double-grind saw blade, operating rope and pulley system, and wing nut for saw attachment. No complex assembly required — extend the pole, lock it, and either pull the rope for the pruner or use the saw blade for larger branches.

Bottom Line

The Fiskars 12’ Fiberglass Tree Pruner/Saw delivers basic functionality at an entry-level price. Perfect for homeowners trimming a few branches each season. Contractors who need daily reliability should spend more on the Power-Lever models or consider chain-drive alternatives.

Fiskars offers a full lifetime warranty against defects in material and workmanship. Given the rope and pulley complaints, you might need it. The tool handles Montana’s ornamental tree maintenance adequately — just don’t expect it to survive heavy commercial use.

Frequently Asked Questions

Q: What’s the actual cutting capacity for different wood types?

The pruner cuts up to 1 inch diameter branches, while the 12-inch saw blade handles thicker limbs. Green wood cuts easier than dead branches. Hardwoods like maple max out the 1-inch pruner capacity quickly.

Q: How does the rope/pulley system hold up in cold weather?

Many users report the rope can fray or snap and plastic pulleys are prone to breaking. Cold makes plastic brittle — expect shorter lifespan if you’re pruning in Montana winters.

Q: Can I buy replacement parts when the rope breaks?

Yes, Fiskars sells replacement parts including saw blade (Part #93356920) and pruner blade (Part #399961). Check availability before assuming you can fix rather than replace.

Q: Is the fiberglass pole better than aluminum for this use?

Fiberglass weighs less than aluminum alternatives, reducing fatigue during overhead work. The trade-off is more flex at full extension, reducing cutting control.

Q: What size branches can the saw blade actually handle?

The 12-inch double-grind saw blade theoretically handles branches up to about 10 inches, but users report the blade wobbles at full extension. Realistic maximum is 4-6 inches for clean cuts.
